===External threats to device lifecycle enhancements===

In the UK, according to ITV (Independent Television), the Met Police (Metropolitan Police) have reportedly threatened the telecommunications industry and phone makers to make phones that are stolen into "unusable bricks", with measures ranging from multi-factor authentication to serializing components within a device to make it harder for them to be salvaged for parts.

Additionally, this news story reports that if efforts are not being made to reduce phone theft by June 1st, 2026, the Met Police will ask for these demands to be enforced at a governmental level, thus further compromising device lifecycle longevity, under the guise of phone theft
